Automation in SignalCalc 900
SignalCalc 900 has the Most Comprehensive Set of Automation Tools for Lab or Production Integration
With a REST based software interface, digital IO, and a built-in automation scripting language – SignalCalc 900 can be easily integrated into an automated lab environment. Take advantage of SignalCalc 900’s powerful data acquisition/control features without losing your workflow or level of automation.
Programmatic REST Interface
Control SignalCalc 900 from any Programming Language – REST is the most commonly used interface for applications to talk. If you are creating software on a computer from this decade, your programming language of choice likely supports REST interface commands. These include Matlab, LabVIEW, Python, C/C++/C#, VB, VBA, and many more.
REST Interface Supports Functionality Such As:
Functionality pertaining to running a single test (e.g. Open, Start/Stop/End, Close, Review a test) as well as getting a list of available tests (e.g. get a list of tests associated with a specific Project from the test database) are all supported through the REST interface.
Read Test Status
Loading test-specific statuses from the currently running test such as whether the test is stopped/running, test time, test level, shaker drive level, or test frequency (sine tests) can all be done through a REST call.
Test Stop/Abort Reason
If a test is stopped, the reason for the stop (e.g. Control Channel abort, or Normal End) can be read through the REST interface.
Creating/Editing a test setup
Create a new test or open an existing test and manipulate test setup parameters; including input channel settings.
Reading Live or Saved Data
The programmatic transfer of time/frequency data (live or already-taken) from SignalCalc 900 is possible through the REST interface. Multiple signals can be requested at a single time, continually, and data can be transferred as text or binary (base64).
Changing a Controller Test Level Live
The test level in a Sine, Random, Shock, Resonance Dwell, or Mixed Mode test can be updated live as the test executes, through REST interface commands. In addition, test schedules can be traversed manually, or the frequency/direction of a sine dwell/sweep can be changed through the REST interface.
Changing an Output Waveform Live
In Analyzer measurements, an output waveform (e.g. Sine or Random) can be changed live through the REST interface. Change the frequency of the sine sweep or dwell; or change the amplitude/phase of the waveform while the test is running.
Read or Write Channel Settings
All input channel settings can be changed programmatically through the REST interface. This can greatly simplify the process of configuring a test with tens or hundreds of channels. An included Excel sample file (with REST functionality included as a Macro) demonstrates this – it grabs all input channel settings from SignalCalc 900 with one click; allows you to modify them in Excel, and then reloads the modified settings back to SignalCalc 900 with a second click.
Test Sequencing and Automation Scripting
Sequencing tests can be done quickly with the Application Sequencer. The Sequencer can quickly sequence tests to run without user interactions needed.
Test Sequences are saved as text scripting files that can be edited in any text editor. This dramatically reduces the time it takes to create even complex sequences, with programmable (if/else, etc.) logic.
Advanced Sequencer and Scripting Features Include:
Sequence a list of tests to run sequentially without user interaction.
Read Test’s Status
Read test’s status and perform actions based on the current state.
Read Digital IO
Read Digital Inputs/Outputs and act on them.
Send Email Notifications
Send email notifications based on test statuses or periodically, for remote test monitoring.
Launch External Applications
Launch external applications based on the vibration test status, digital IO, or time.
Control your Entire Lab
With programmatic functionality, scripting, reading test status, and reading/writing Digital IO – you can integrate controls of many different systems from SignalCalc 900.
Plug and Play Functionality
Simple IO such as signaling test status or receiving a stop signal.
Control Thermal Chambers
Digital Inputs/Outputs can easily be used to command a thermal chamber; and to wait for a response signal from the chamber indicating it is at temp.
Display Within SignalCalc GUI
LED Displays within the software show the state of the Digital IO.
Simple Programmable logic
Turn outputs On/Off; wait for a response, or perform actions when a specific input is turned on from within the Application Sequencer.
Complex Programmable Logic
Create a custom interface with more complicated logic using the Automation Scripting language; including the use of loops, conditional statements based on digital Inputs’ state and/or the currently running vibe test’s state (see screenshot to the left).
